Hi,
here is a patch-set to replace the dev->iommu_group checks in the source tree by a proper function call. The pointer checks mostly happen to check whether a device is managed my an IOMMU. For that purpose a pointer check is not very descriptable, so replace it by a function call that make its purpose readable.
This also starts to remove direct access to the dev->iommu_group pointer outside of iommu-code. This is another move towards consolidating the various iommu-related pointers in 'struct device' into one pointer only.
Please review.
Thanks,
Joerg
